Congratulations on your purchase of a fine, hand-built, Basslines bass guitar pickup! Installing this pickup
in your bass isn’t rocket science. And, if you’re already handy with tools, it’ll be a snap for you–and fun
too! But if you have no experience handling red-hot soldering irons, you’d be well advised to take your
new pickup and your trusty bass to a qualified guitar tech.
The basic steps for installation include:
1. Remove the strings from your guitar.
2. Remove the control plate and flip it over.
3. De-solder the original pickup’s wires from the controls, and make sure to remember where
they were connected.
4. Remove the original pickup from the pickup cavity.
5. If your original pickups were passive (no wires connecting from the pickups to a battery),
remove the original pots and output jack, and replace them with the provided 100k pots
and stereo output jack---you will re-use the capacitor from your original tone control.
6. Install the new 100k pots and stereo jack, and connect them as shown.
7. Tin the wires from your Basslines pickup, and solder them into place.
8. Connect the two battery clips in series (refer to diagrams).
9. Connect the red wires from all pickups to the red wire from the first battery clip.
10. Connect the remaining black wire from the second battery clip to the ring terminal of the
output jack.
11. Replace the control plate, taking care to tuck in any loose wires.
12. Re-string your bass and adjust the pickup height so that your pickups are about 1/8” from
the strings when they are pressed down at the highest fret on the neck. For basses with two
pickups, adjust the bridge pickup’s height first, and then set the height of the neck pickup so
that the outputs of the two pickups balance properly.
